Abstract
The present invention relates to compositions and systems comprising peptide-based reagents for delivery of cosmetic benefit agents to human hair, human skin, or human nail.
Claims26
A cosmetic system comprising:
- a peptidic component comprising at least one binding domain which binds to at least one of human hair, human skin or human nail with a Kd or MB50 value of 10−5 molar or less and which further comprises the first part of an affinity pair;
- and
- a stable dispersion of particulate benefit agent having average particle size of between about 0.01 micron and about 75 microns and the second part of the affinity pair;
- the at least one binding domain has a greater binding affinity for the human hair, skin or nail than it has for the particles of the dispersion.
1 more element
A method of applying a benefit agent to at least one of human hair, human skin, or human nail comprising:
- contacting the human hair, skin, or nail with a composition comprising a peptidic component having at least one binding domain which binds to at least one of the human hair, skin, or nail with a Kd or MB50 value of 10−5 molar or less, and which further comprises the first part of an affinity pair, for a time sufficient for the binding domain to bind to the human hair, skin, or nail;
- and
- subsequently applying to the human hair, skin, or nail a stable dispersion of particulate benefit agent having average particle size of between about 0.01 micron to about 75 microns and the second part of the affinity pair;
- wherein the at least one binding domain has greater binding affinity for the human hair, skin, or nail than it has for the particles of the dispersion.
